Analysis of 18 as acceptor substrate of TcTS. A: 18 (1 mM) and 3’-sialyllactose (SL, 1 mM), without enzyme; B: 18 (1 mM) was incubated with SL (1 mM) and TcTS for 15 min at 25 °C; C: the same as B but using 2 equivalents of SL (2 mM). The incubation mixtures were analyzed by HPAEC using a CarboPac PA-10 ion exchange analytical column eluted with a linear gradient over 30 min from 20 to 200 mM NaAcO in 100 mM NaOH at a flow rate of 0.9 mL/min. Structures for compounds 18, 25 and 26 are shown in Scheme 4.
